Notes on Microphone System Operation
•
In a system using twelve or fewer microphones, maintain
a distance of at least 30 cm (1 ft) between each pair of
microphones, and a distance of at least 3 m (10 ft)
between each microphone and its receiving antenna.
For details of operation with two or more channels, refer
to the Operating Instructions for the WRR-810A UHF
Synthesized Tuner and the WRR-840A/860A UHF
Synthesized Diversity Tuner.
•
Ensure that the tuners set to channels not being used are
either turned off or set to the minimum output level (the
LEVEL adjustment knob set to MIN).
•
When powering the microphone on or off, to keep the
noise to a minimum, set the audio output level from the
tuner or mixer to a minimum.
•
Powering the microphone on without checking the
channel selection first may interfere with the operation of
other microphones/transmitters, if the current setting is
already being used.
